6. Construct a parallelogram ABCD in which AB=6.5cm, AC=3.4cm, and the altitude AL from A is 2.5cm. Draw the altitude from C and measure it.

Solution:

RS Aggarwal Solutions for Class 8 Mathematics Chapter 17-image12

We know, AB=6.5cm, AC=3.4cm, AL=2.5cm

From the above figure the construction is not possible. So we have to find the altitude using from D.

Length of the perpendicular from A on DC= AL= 2.5cm (since the perpendicular length is the same on both side).

∴ The length of the perpendicular from D on AB=DM= 2.5cm.

7. Construct a parallelogram ABCD, in which diagonal AC=3.8cm, diagonal BD=4.6cm and the angle between AC and BD is 60o

Step3: At O draw ∠COX= 60o

Step4: Set the value OB= 2.3cm and OD=2.3cm (divided the value 4.6 into 2.3 and 2.3)

Step5: Now join AB,BC,CD,DA

∴ The constructed parallelogram looks like:
